There should be no trouble finding a Qb3 for a driver with that Q

Is that the parameter set you are requiring to be entered? It seems that using just: Fs, Qts, (Qes or Qms), Vas, Re, Dia, you can calculate the others. A fair # of drivers don't come with a Qms or Qes and you can just guess Qes as something larger than Qts (or similarly set Qms to ~3 when it is not entered). Cms and Mms or even Sd are also not commonly provided or given in potentially confusing units.

QB3 for this driver (depends on Ql of box) will be ~1.83L, 89Hz tune with ql=7.

Yes you are right, AENEAS finds exactly the values you mentioned for QB3. I was wrong. It is not QB3 it is C4 that causes the trouble. And since C4 is the first item in the list the app enters an infinite loop, when trying to solve the design equation...
Anyway I'll fix that.

SC4 doesn't really work below Qts~0.26 or so. Maybe need to add some error checking C4 is for k<1.

Finally Apple has approved the Hotfix for the reported issues. It should be available for free for owners of AENEAS. Enjoy it.
If you have ideas or you find another bug please let me know. Your are welcome!

I have some great news:
Finally the App Store review team has approved the iOS version of AENEAS.
You can now get via the App Store and run it on your iPad.
I am looking forward to read your feedback!

support for multiple drivers in a single enclosure would be fantastic!
